The Double Tough Challenge consists of two rides over two days, Saturday's Gran and Sunday's Medio, for a grand total of 160 miles. To participate, you must register specifically for the Double Tough Challenge during registration. Finish your ride before courses close on Saturday and Sunday to earn the exclusive (and elusive) Double Tough Jersey.

 

There will be timing points along each route to verify the completion of both distances. If you complete the Double Tough Challenge, CONGRATULATIONS! Report to the Mumu tent at the SFTT Expo immediately after your Sunday ride to try on jersey samples and register your size. Your award jersey will be shipped to your address approximately 8-10 weeks after the event date.
